Title: Improvements in and relating to aeroplanes
IPC: B64C3/52
Filed: 1919-04-10
Abstract: 147,971. Christmas, W. W. April 10, 1919. Steering, balancing, and regulating altitude; planes and the like, construction of and connecting to machine.-A flexible wing without internal wiring or external struts and wiring is constructed with a main spar of decreasing stiffness from root to tip which yields and moves in a vertical plane to change the dihedral angle and is also capable of a twisting motion under torsion to produce change in the incidence and camber. The trailing portion of the wing is also independently flexible. When the machine is stationary, the wings have a negative dihedral, and when in motion the wings take up a positive dihedral of maximum value towards the tips. In a multiplane machine, all the wings may be flexible or some may be of the usual rigid construction. Each wing 7 comprises two main spars 12, 13, a leading-edge spar 11, a flexible rear spar 14, and ribs 10, Figs. 4 and 5, the trailing surface being formed of flexible laths 17 passing to a flexible trailing-edge spar 18. The cantilever spars 12, 13 are close together on either side of the mean position of the centre of pressure, and are connected at the top and bottom by plates 19 forming a single composite box spar, rigid in the horizontal plane against drag forces but flexible in the vertical plane and capable of twisting as indicated m Figs. 21 and 22. Each spar is built up of wood laminations with metal-plate reinforcements 21, 22, Fig. 12, the outer plate 22 extending a small distance from the fuselage and the other plates 21 extending outwardly about two-thirds the length of the spar. The outer part 23 of the spar is wood only and is lightened and made more flexible by holes 24. Strips of veneer 27 may be used between the leading edge 11 and the spar 12 forming a smooth backing for the fabric wing covering 9. For attaching the wings to the fuselage, clamps 28 of U section. Figs. 8 and 10, are employed. These have triangular sides 32 and rectangular top plates 33, which fit over the ends of the spars and are bolted to lugs 29 on a longitudinal 30, the latter being parallel to the top longeron 38 and attached to two of the fuselage struts 37 by brackets. Instead of the clamps 28 being bolted to the longitudinal 30 direct, they may be bolted to jaw-faces slidably mounted on the longitudinal, which is then preferably of T- section; the planes may thus be adjusted to any desired fore and aft position and fixed there by tightening the bolts of the jaw-pieces.

Abstract: 1,168,421. Mixing solids with fluids in flow. A. J. CLEARY and K. F. KEEFE [trading as CLEMCO-CLEMENTINA Ltd.] 26 Feb., 1968 [6 March, 1967], No. 9184/68. Heading BIC. [Also in Divisions B8 and F2] A device for introducing granular material. such as sand, into a fluid stream and comprising a housing 10, formed with inlets 86, 88 for the material and for the fluid stream and an outlet 90, is provided with a pressure sensitive device which is connected to a valve member 54 and which is arranged to open the valve in proportion to the fluid pressure in the housing. The pressure sensitive device comprises a flexible diaphragm 16 to which are secured a piston 18 and a rod 20. The diaphragm is urged downwardly by a spring 62 and a second spring 68 is mounted within a bore in a member 64 screwed into the housing portion 12 whereby the position of the spring 68 relative to the diaphragm may be varied, a scale 84 being provided on a pivoted handle 80. The diaphragm is connected by a rocker arm 34 to a hexagonal-section rod 44 which is slidable in fixed guides 48, 50 and which carries the valve member 54. The handle 80 may be positioned, as shown, to engage the rod 20 to hold the valve member in the closed position. In operation, the handle is moved to free the rod, fluid pressure in the housing causes the diaphragm to move upwardly, against the action of the spring 62, in a valve opening direction. On further upward movement of the diaphragm, Fig. 3 (not shown), the second spring 68 having a rough higher spring constant, is brought into play. The movement of the diaphragm against the action of spring 68 is proportional to the pressure in the housing and therefore the rate of fluid flow through the housing. The valve aperture 56 is of a flare shape, Figs. 1, 1A (not shown) and arranged so that the larger the initial opening of the valve, produced before the spring 68 comes into play and determined by the position of the member 64, the greater the increase in valve opening available.
